"What a night," the award-winning actress writes alongside a video that shows the envelope which lists Urban’s name as the big winner. "We were so shocked. Congratulations baby."

Keith's Win Was One of the Best Moments of the 2018 CMA Awards

A short time after, Kidman could still be heard squealing in the background as Urban issued a video thank you to his fans from the couple's Nashville-area home.

"Hey everyone, it’s Keith here," Urban says in an Instagram video before grabbing a quick kiss from Kidman. "We just got home from the epic CMA Awards tonight and just thank you. I want to say thank you to everyone that voted and all the fans — you are phenomenal. You have no idea how much this award means to me."

After a long embrace in the seats, Kidman received much love from Urban in his acceptance speech, most of which was said while tears streamed down both of their faces.

"Baby girl, I love you so much," Urban said from the stage during his EOTY speech. "Thank you for supporting me and loving me through all that I do."
